[PKT_SCHED]: Make sch_fifo.o available when CONFIG_NET_SCHED is not set.
Based on patch by Patrick McHardy.
Add a new option, NET_SCH_FIFO, which provides a simple fifo qdisc
without requiring CONFIG_NET_SCHED.
The d80211 stack needs a generic fifo qdisc for WME. At present it
uses net/d80211/fifo_qdisc.c which is functionally equivalent to
sch_fifo.c. This patch will allow the d80211 stack to remove
net/d80211/fifo_qdisc.c and use sch_fifo.c instead.
